For those punters who failed to see the potential behind Prince Of Johanne, the 40-1 winner of the Cambridgeshire here on Saturday, it may be some consolation to know that the owner is a professional gambler who was as surprised as anyone else to find himself lifting the trophy. "We honestly thought we couldn't win, because of the draw," said David Storey, a 40-year-old who has never worked outside the betting industry.

The reason for his pessimism was Friday's Silver Cambridgeshire, when those involved in the finish raced against the far rail, whereas Prince Of Johanne was due to start from stall 31 of 35, close to the stands' rail. Bafflingly for those trying to find the winner, that proved the right place to be.

Storey, who owns this horse and one other jointly with a schoolfriend, has made his money by in-running gambling on Betfair but says he has been much less busy since that firm introduced a premium charge for their most successful players this year. "I've had quite a few weeks off in the summer with the school holidays and things," he said. The prize money of £77,000 would, he added, reduce the pressure on him to get involved once more.

For the winning trainer, Tom Tate, this was a first winner for 71 days. "I could tell you he's been laid out all season for this but he hasn't," he said.

Based in Tadcaster, Tate was the nearest thing to a local success in the major races, Irish horses carrying off the first two Group races and a French runner, Sahpresa, landing the Sun Chariot for the third time. That victory added to the quite astonishing record here of her jockey, Christophe Lemaire, who was winning his seventh Group One on the Rowley Mile. Lemaire said this would serve as a timely confidence-booster ahead of his ride on Sarafina, favourite for next Sunday's Arc.

Aidan O'Brien was also asked about the Arc after training the first three home in the Royal Lodge. "So far so good," was his report on the wellbeing of So You Think, a 5-1 shot for the Longchamp contest. A decision as to who will ride will be made next week.

The British Horseracing Authority may be prepared to contemplate a change to the rules as to who gets punished when a jockey weighs in light. Kieren Fox was given a four-day ban at Kempton this week when he weighed in light but his colleague Richard Hughes protested in Saturday's Racing Post that the ban was "wrong" and that jockeys should not bear sole responsibility for the contents of a saddle that is out of their control for 10 minutes after weighing out.

Trainers have sometimes been punished in cases where there has been clear evidence of fault, as when John Akehurst forgot to attach the weight cloth to the saddle before Capricho was in a dead-heat for first in the 2002 Bunbury Cup. However, in the absence of evidence, only jockeys are punished.

The BHA's spokesman Paul Struthers said that Fox had not submitted an appeal and suggested that there might be fewer than 10 instances each year of a jockey weighing in light. However, he added: "If the Professional Jockeys' Association wants to bring it up at the end-of-season meeting we always have with them, we'll look at it."
